		+	You must configure the 6 to 4 relay tunnel on an Internet-facing interface. Doing this on a computer behind a NAT will not work.
		+
		+	A 6 to 4 tunnel derives your IPv6 address from your IPv4 address. To figure out what it is, just convert your IPv4 address to hexadecimal and prefix it with 2002 (8194 in decimal). This produces a 48-bit prefix. In IPv6, networks are 64 bits wide, and the other 64 bits of the 128-bit address is the host portion. You are free to assign the next 16 bits for up to 65,535 networks. Well, the first network, zero, will be used as an external gateway to your IPv6 internal network. If you don't know which IP to use, it is the one associated with your default route. If you don't know that, try this:

		+	lynx -dump www.whatismyip.org
